PATTERN-CARD FOR LOOMS.

No. 909,078. Specification of Letters Patent. Patented Jan. 5, 1909.

Original application filed March 9, 1907, Serial No. 361,613. Divided. and this application filed. April 3, 1908.

. Serial No. 425,020.

To all whom it may concern: I openings, in such a manner that they can Be it known that I, JEAN (30111, a subject i be easily brought at one or the other end of of Belgium, residing at Ensival, near Versaid openings, leaving a portion of the openviers, Belgium, have invented new and useful ing free or unobstructed for the passage of a Improvements in Pattern-Cards for Looms, l needle. The stop members can thus be disof which the following is a specification. tributed in two ranges, one comprising stop This invehtion relates to pattern-chains members in operative position and one comused in connection with looms and has for its 5 prising stop members in inoperative position. purpose to provide a simpler structure than The stop-members are locked in each of said hitherto used comprising a minimum of positions by means of a locking member 10 parts, althou h allowing the production of any pattern W iatever and without requiring the use of separated or additional members.

With this object in view the invention consists mainly in special combinations and arrangements of parts as hereinafter fully described and pointed out in the appended claims.

In the annexed drawings: Figure 1 is a top view of two plates or lags making part of a pattern-chain constructed according to the invention. Fig. 2 is a transverse section of one of the plates of the card. Fig. 3 is a separate view of a locking member used in combination with the plates of the card. Fig. 4 is a transverse section of said locking member. Fig. 5 is a se arate view of one of the stop members use( in connection with the plates.

To carry the invention into practice, the pattern chain is composed of lags each formed of a plate 1 provided with openings 2, the major axis 3 of which is preferably at right angles with the longitudinal axis of the plate 1 and extends to substantially the same length on both sides of said longitudinal axis. The said openings 2 extend consequently crosswise or substantially crosswise of the card and are distributed parallelly to each other over the length of the late 1. In each of said openings 2 is place a stop member 4 adapted to slide back and forth in said opening, said stop members being in the form of a little grooved roller 5 (Fig. 5) or formed by washers or small plates 6 of anp; shape, but preferably round, provided wit a central pin 7 passing through one of the openings 2 and projecting on the other side of the plate 1 to receive a similar plate or washer 8 suitably riveted or otherwise fitted to the in 7. p When the grooved rollers 5 have been in troduced one in each opening 2 of the plate 1, they are adapted to slide in the said openings, being guided by the dges 9 of said shown separately Figs. 3 and 4 and consisting of a needle, sli htly curved and adapted to be engaged wit in a certain number of raised eyes 11 suitably stamped or otherwise formed on one face of the plate or lag 1. The said locking member is provided near its middle with a notch 12 in such a manner that when it is passed through the raised eyes 11 of plate 1, one of said eyes suitably located near the middle portion of the plate can be engaged in said notch 12, thus preventing any longitudinal displacement of the needle 10; the said needle then bears with its ends 13 on the surface of the plate 1 while its middle portion acts as a spring to prevent any disengagement of the notch 12 from the corresponding eye 11.

In order to secure a better engagement of the needle 10 with the eyes 11 and also to prevent its rotation the said needle is preferably provided, as shown in Fig. 4, with a lower flat surface 14 adapted to rest upon the surface of the plate 1 and with a circular surface 15 engaging the eyes 11. When said needle is passed through the eyes 11 and is laced in its operative position on the surface of the plate 1, it projects from said surface alon the longitudinal axis of the plate and thus ocks the several stop members 4 in their predetermined positions.

Consequently when it is desired to vary the pattern which is to be produced, it is merely necessary to depress slightly the middle raised portion of the needle 10 so as to disengage the notch 12 from the corresponding eye and to displace the needle longitudinally thus leaving free the passage in each opening 2 for the movement of the several stop members 4. The said stop-members are then suitably distributed in their operative and inoperative positions and afterwards the needle is again passed through the eyes 11 as before described, thus locking the stop members in their new positions.

Each plate or lag 1 is provided at both ends with a groove 16, the direction of which is preferably at right angles with the longitudinal axis of the plate, and each of said grooves is combined with an opening or passage 17 giving access to the corresponding groove 16. The said openings or passages 17 are in alinement with each other and with the raised eyes 11 in such a manner that the ends 13 of the locking member or needle 10, when said needle is put in position on the plate 1, close the openings or passages 17 thus preventing rings 18 from falling out of the grooves 16. The said rings 18, which are introduced into the grooves 16, when the ocking member or needle 10 is removed from the plate 1 serve as means for connecting together the several plates or lags 1 of the pattern-chain.

As is obvious each lag of the pattern chain comprises only one plate 1 provided with openings 2 and unremovable stop members 4 located in said openings and a detachable locking member 10 acting simultaneously as a locking member for the rings 18. The stop members 4 being unremovable the card-chain can be conveniently appropriated to any pattern without any dismantling and with a very simple manipulation.

The movement of the card chain may be effected by means of projections engaging openings 19 or, better still, by means of projections engaging directly in the space between two consecutive parts of the card chain.

Having thus described my invention, what I claim is:

1. In a pattern-chain, the combination of a unitary plate provided with a plurality of parallel openings, an unremovable needlestop member adapted to slide in each of said openings, but of less size than the opening so t at a portion only of each opening is obstructed, and a locking member holding the said stop-members either in operative or in inoperative position, whereby a needle may enter the unobstructed portion of said openmg.

2. In a pattern-chain, the combination of a unitary plate provided with a plurality of openings positioned at an angle to the longitudinal axis of the plate, a grooved stopmember adapted to slide in each of said openings, and a locking member cooperating with said stop-member, each stop-member partially obstructing one opening in said plate and leaving the remainder of said opening free or unobstructed.

3. In a pattern chain, the combination of a single plate provided with a plurality of parallel openings, the major axis of which being at right angles with the longitudinal axis of the plate, unremovable stop-members adapted to slide each in one of the said openings and a locking member holding the said said openings and to close a portion of said openings, and a locking member extending lengthwise of the plate.

6. In a pattern-chain, a unitary plate provided with slots extending crosswise thereof, a needle stop-member cooperating with each of said slots and of less diameter or width than the length of said slots, occupying a part only of each slot and leaving the remainder of the slot unobstructed, whereby said stop-member may be adjusted in variable positions in the slot, and a locking member extending lengthwise of the plate and adapted to hold the stop members in their adjusted positions.

7. In a pattern chain the combination of a single plate provided with openings extending crosswise of the said plate, unremovable stop-members adapted to slide back and forth in the said openings and to close a portion thereof, a locking member extending lengthwise of the plate and holding the stop members in a predetermined position in the openings of the plate, whereby a portion of said openings is left unobstructed, and looking means for said locking member.

8. In a pattern-chain the combination of a single plate provided with openings extending crosswise of the said plate, unremovable stop-members guided by the edges of said openings, the diameter or width of each stop member being less than the length of one opening and each stop member being adapted to slide back and forth in the said openings thereby closing a portion thereof, a locking member extending lengthwise of the plate, and holding the stop members in a predetermined position, and means for holding the said locking member on the surface of the plate and looking it in position. 9. In a pattern-chain, the combination of a single plate provided with openings extending crosswise of said plate, unremovable stop members passing through said openings and guided by the edges of said openings, raised eyes formed on the surface of the plate, a needle passing through said eyes and preventing the displacement of the stop members in their respective openings and means for locking the needle in position.

10. In a pattern-chain the combination of a single plate provided with openings extending crosswise of said plate, grooved rollers sliding in the said openings and closing a portion thereof and a locking member extending lengthwise of the plate along its middle axis, and means for locking the said locking member in position.

11. In a pattern-chain the combination of a single plate provided with openings extending crosswise of said plate, grooved rollers sliding each in one of the said openings, the edges of said openings being engaged in the grooves of the rollers, raised eyes formed on the surface of the plate and a locking needle passing through said eyes.

12. In a atternchain the combination of a single p ate provided with openings extending crosswise of said plate on both sides of the longitudinal axis of the plate, stop members sliding each in one of the said members in the openings from one to the opher side of the longitudinal axis of the p ate.

13. In a pattern-chain the combination of a plate provided with openings extending crosswise of said plate on both sides of the longitudinal axis of the plate, grooved rollers engaged in said openings and having projecting portions on both sides of the plate, the said rollers closing a portion of the corresponding openings, grooves at each end of the plate, connecting rings in said grooves and a needle locking the grooved rollers either in operative or inoperative position and simultaneously preventing the connecting rings from falling out of the grooves in which they are engaged substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
